LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 419,747, dated January 21, 1890.

Application filed July 5, 1889. Serial No. 316,570. (No model.)

To all whom it may concern:

Be it known that we, LEWIS J. A'rWooD and FREDERICK W. TOBEY, of Waterbury, in the county of New Haven and State of Con- 5 necticut, have invented an improvement in Lamp-Burners, of which the following is a p specification. L Our present improvements are adapted to f large lamp-burners, especially those having to two flat wicks for producing intense and large llames. The burner is rendered very compact by our improvements, and it is not liable to heat or tc be injured in use.

In the drawings, Figure 1 is a vertical section at the line :r of Fig. 2. Fig. 2 is a plan view with-the chimney-holder removed. Fig. 3 is a section of the burner at the line y y of Fig. 2. Fig. 4 is a detached view with the wick-raiser shafts in section, and Fig. 5 is a zo partial section of a modification.

The wick-tubes 2 2 are of any desired size, according to the Wick made use of. The base B of the burner is a metal shell that is cylindrical at 3, and drawn in conically at 4, and 2 5 provided with a screw at 5 for securing the burner to the collar on the reservoir, and where the burner is also adapted to a largesized screw-collar on the lamp-reservoir there is to be a screw-thread at 6 around the base 3c or shell B.

At C is a cap or cover to the shell B, usually known as the ratch et-cap, with large sizes of wick-tube, and especially where two wicktubes are applied in one burner the screw 3 5 portion 5 is usually large enough for the wick or Wicks to pass through freely in a partiallyfolded condition, but not large enough for thewick-tube to pass inte such screw portion l 5. lVe therefore insert in the shell B a dia- 4o phragm 7, perforated at the proper place or places for the wick tube or tubes to pass into the same and be secured in place by such diaphragm 7 andthe ratchet-cap C, and it is preferable to turn up the edges of this diaphragin to fit the interior of the cylindrical portion 3 of the shell B, and the parts can be made tight and strong, and heat is not conducted down to the reservoir as rapidly as it is when the tubes pass into the cylindrical screw 5.

Around the shell B, and preferably as an extension of theratchet-cap, is the annular air-distributer 8, with a hanging ledge 9 for the surrounding cylindrical air-distributer 10, which is continued upwardly and forms the dome or deflector D, with the flame-slots 1l above the respective wicks, and thereare air-holes at 12 around the base of the deflector D. The chimney holder or rest E surrounds the base of the deflector D, and above the holes of the airdistributer 10, and this chimney-rest has a row of springs 13 for holding the chimney, and an inner flange 14, that serves to connect the chimneyrest to the deiector, the flange 14 fitting tightly as the chimney-rest is pressed down t0 place around the deflectcr, and it is preferable to have a shoulder or offset in the cylindrical part of the deflector-base for the chimney-holder to rest upon, and solder or projections maybe used for holding the chimney-rest firmly upon the defiector. Vithin the deflector D is a secondary air-distributer F, which in Fig. 1 is shown as slotted for the passage of the wick-tubes, the perforated sheet metal being turned down to form flanges 15, at the sides of the wick-tube, for rendering the attachment more reliable, especially when solder is applied to the flanges 15 and wicktube. In Fig. 5 this secondary air-distributer is represented as conical with its lower edges fastened to the ratchet-cap.

The edges of the elevated air-distributer are turned down-to form the rim 16, that sets tightly around within the movable deflector D, and the annular corrugations 17 stiffen the elevated air-distributer.

The wick-raising Wheels G are within the shell B, and act through slots in the Wicktube, and the shafts 18 pass out and terminate with thumb-wheels 19. The shafts 18 pass through Vnotches in the hanging ledge 9, and the lower edge of the air-distributer 10 is also notched for these shafts 13. The object of doing this is twofold. It insures the removable chimney-holder and deiiector being restored to the proper place for the slots 11 to come over the wick-tubes, and when the burner is grasped for screwing or unscrewin g the same upon the reservoir there is no risk of bending or injuring the shafts 18, or of the chimney-holder rotating on the other parts of the burner, because the shafts 1S prevent the chimney-holder moving without the base or shell, and the hanging ledge 9 supports the shafts 18 adjacent to the notched air-distributer 10.

The air passing up to the flame is effectually regulated, because the currents of air passing in horizontally through the holes of the cylindrical air-distributer 10 are met by the ascending currents of air through the dis- .tribnter 8, and they mutually check each other and prevent the flame iiickering, and this is further promoted by the secondary airdistributer F, and should any gases be generated in the lamp the fine perforations in the distributer F, when in the form shown in Figs. 1 and 3, prevent flame passing to the reservoir.

Extinguishing-lids 2O are hinged to the sliding sleeves 21, that surround thel wick-tubes 2, and these are connected to the lifter 22, that passes through theelevated air-distributer F and the ratchet-cap C, and there is a lever H, that is made use of for raising the sleeves to allow the lids to drop and extinguish the iiame, or the sleeves are moved downwardly for taking the lids off the wiel' s.

In burners of the present character the lever H could not be applied at the side of the burner, as has beenusual, and allow for removing the chimney-holder and deiiector. I therefore enter this lever H below the airdistributers through a slot in the shell B and pivot the lever at 25 on the under side of the air-distributer 8, the end of the lever projecting sufficiently to allow it to be moved freely in operating upon extinguishers.

We claim as our invention- 1. The combination, with the burner base or shell B, having the screw 5 for the reservoir and the wick-tube 2, of the separate diaphragm 7 within the base, through which the wick-tube passes, and the ratchet-cap forming. the top of the shell, substantially as set forth.

2. The 4burner-shell B, having the screw 5, the wick-tube, the ratchet-cap, and an airdistributer 8, and hangingledge 9 around the shell,in combination with the cylindrical airdistributer 10, deflector D, and chimney-rest E, connected together and removable from the air-distributer S, substantially as set forth.

3. The burner-shell B and the stationary air-distributer S around the same, and the hanging ledge 9 around such air-distributer, in combination with the removable cylindrical air-distributer 10, resting on such ledge, the deflector D,rising above the air-distributer and slotted for the frame, the chimneyrest E, surrounding the defiector and projecting beyond the air-distributer 10, and the secondary air-distributer F within the deflector, substantially as set forth.

4. The combination, with the burner-shell, wick-tube, wick-raising wheel, and shaft, of an air-distributer around the burner-shell notched for the shaft of the wick-raiser, and a removable air-distributer and deflector, also notched for the wick-raiser shaft, substantially as set forth.

5. The combination, with the burner-shell having two screws 5 and 6 thereon, the wicktube, and the ratchet-cap, of an air-distributer around the shell having a hanging ledge, the wick-raiser and shaft, the latter passing through the hanging ledge, the removable airdistributer 10, notched for such shaft, the deiiector, the chimney-holder surrounding and projecting outside the base of the defiector, and the secondary air-distributer within the deflector, substantially as set forth.

6. The combination,with a nearly horizontal air-distributer and hanging ledge around the burner-shell, of a removable cylindrical air-distributer rising from the edge of the nearly horizontal air-distributer, a dome or dei'lector connected to the cylindrical air-distributer, and a secondary air-distributer connected to the wick-tube and having an edge which is within the lower part of the deflector, so that the currents of air passing in horizontally and vertically commingle and then pass vertically through the secondary airdistributer, substantially as set forth.

Signed by us this 29th day of June, 1889.
